"Mommy loves you more than I can ever show you. You are part of MY SOUL forever," she said.

"I miss you so much everyday. I wish I could wake up and have you here with me. I miss your smile, your hugs and your giggles. I miss EVERYTHING about YOU, Gigi. I LOVE YOU so much!!!!!!!"

In a second post the mother-of-four asked others to wear red to celebrate her daughter.

"Gianna loved to wear a red bow in all of her school pictures. Red means love and life.

"To commemorate Gigi's birthday today, please consider wearing red, caption an act of kindness or show how you will play Gigi's way since she always gave everything she did her all and led with kindness," Vanessa wrote.

Like her dad, Gianna was a talented basketball player and was known as Mambacita, a Spanish-language spin on her father's famous nickname, Black Mamba.
